UNITED STATES PATENT OFFICE. I

GUST LARSEN AND EDWARD BRASSEL, OF CHICAGO HEIGHTS, ILLINOIS.

AIRSHIP.

Specification of Letters Patent. Patented Sept. 5,1916.

Application filed December 17, 1915. Serial No. 67,458.

To all whom it may concern Be it known that we, GUST LARSEN and EDWARD BRASSEL, citizens of the United States, residing at Chicago Heights, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Airships; and we do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use'the same.

The invention relates to improvements in air-ships.

The object of the present invention is to improve the construction of air-ships, more especially the means for supplying the air to the cylinder for actuating the-mechanism for propelling the ship and for other pur-= poses and to provide a simple, practical and comparatively inexpensive construction disposed at opposite sides of the air-ship and adapted to maintain the equilibrium of the same, without interfering with the steering and propulsion of the same,

With these and other objects in view, the

,invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes may be resorted to without departing from the spirit and scope of the appended claims.

In the drawings, Figure 1 is a side elevation of an air ship constructed in accordance with this invention. Fig. 2 is a rear elevation of the same. Fig. 3 is a detail perspective view illustrating the arrangement of the central distributing pipe or chamber.

Like numerals of reference designate corresponding parts in the several figures of the drawing.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, the flying machine comprises in its construction, a substantially cigarshaped bag 1 having tapered front and rear portions 2 and 3 and provided at its rear portion with a propeller 4:, suitably fixed to a propeller shaft 5 extending from the apex of the rear portion 3 of the bag and which may be supported in any desired manner. The propellerfl may be equipped with any desired number of blades and the shaft 5 has keyed or otherwise secured to it sprocket Wheels 6 which are connected by sprocket chains 7 with the air-ship will sprocketwheels 8 of side shafts 9 extending longltudinally of the bag 1 from the rear end of the same to the front portion thereof and Ournaled in suitable bearings. The frame work may be of any desired construction and the side shafts which are preferably located slightly below the horizontal plane of the propeller shaft 5 are provided with crank bends 11 set at different points and connected by a pitman 12 with piston rods 13. The piston rodsare provided with heads 14 which operate in cylinders 15. The cylinders 15 are equipped withvalve stems 16 having suitable valves which are connected by rods 17 with eccentrics 18 mounted on the side shafts 9. The pistons are operated by compressed air and the valve chests'are connected by pipes 19 with a tube 20. A.

distributing tube 20 is located at each side of the air-ship and is connected with a centrally arranged air tank 21 by a transverse pipe 22 and admission of compressed air from the tank to the transverse pipe 22 is controlled by a suitable valve 23 having an operating stem 24 which is equipped with a suitable hand wheel 25. The compressed air will be supplied to the tank by a suitable air compressor not shown, with which be equipped and the airship is provided with a suitable car 26 suspended from the frame work 27 which, is suitably connected with the cigar shaped bag 1. By arranging the cylinders atintervals at opposite sides of the air-ship, the two sets counter-balance each other and they may be conveniently operated by gearing connecting them with the propelled shaft.

The cylinders are arranged at intervals and extend upwardly and outwardly at opposite sides of the air-ship and the distrlbuting tubes which also extend longitudlnally of the air-ship are located at opposite sides of the central air tank so that a single connecting pipe and a single valve may control the discharge of air from the compressed air tank to the distributing tubes.

Whatds claimed is r 1. An air-ship including a bag, longitudinal shafts located on opposite sides of the bag and provided with crank bends, a series of cylinders located on opposite sides of the air-ship and provided with pistons extending upwardly and connected with the crank bends, distributing tubes located at opposite sides of the air-ship, extending longitudinally thereof and provided with means for supplying the cylinders with compressed air, a compressed air tank and means for controlling the flow of compressed air from the tank to the distributing tubes. 4

' 2. An air-ship including a bag, side shafts located at opposite sides of the bagv and provided with crank bends, a seriesof cylinders located at each side of the air-ship and having pistons connected with the crank bends, a centrally arranged compressed air tank located beneath the bag, longitudinal distributing tubes connected with the air tank, and provided with means for supplying the cylinders with compressed air, a pipe connecting the distributing tubes with the compressed air tank and a single valve for controlling the discharge of compressed air from the tank.

In testimony whereof we aflix our signatures in presence of two witnesses GUS. LARSEN. EDWARD BRAS SEL.
